Definitions
- the invention relates to an electrical circuit arrangement comprising a first inverter and a second inverter. Furthermore, the invention relates to an electric drive arrangement.
- power electronic circuits are used in the electric drive trains, which circuits include one or more inverters.
- a direct current which is taken from an energy store designed as a traction battery, for example, can be converted into an alternating current for operating an electric machine when the motor vehicle is in operation.
- an inverter can also be used to rectify an alternating current generated by the electric machine in generator mode, so that the traction battery of the motor vehicle can be charged, for example, in recuperation mode.
- Two inverters can be used, for example, to drive two electrical machines, each driving a wheel of a common axle of the motor vehicle.
- the two inverters which are each assigned to one of the electrical machines, are provided as part of the axle or of a motor vehicle and must be arranged in the motor vehicle.
- this has a disadvantageous effect on the installation space required inside a motor vehicle, since with two inverters the other components are usually also duplicated in each case.
- the invention is therefore based on the object of specifying an improved electrical circuit arrangement with two inverters, which in particular is more compact Execution and thus a space-saving arrangement of the electrical circuit he allows.
- the invention provides that the electrical circuit arrangement comprises a housing with a plate section extending inside the housing, the plate section dividing the interior of the housing into a first chamber and a second chamber, with a first side of the plate section the first chamber at least partially bounds and a second side of the plate portion opposite the first side at least partially bounds the second chamber, the first inverter and the second inverter each comprising at least one power module and the power module of the first inverter on the first side of the plate portion and the power module of the second inverter is arranged on the second side of the plate section.
- the at least one power module of the first inverter which is arranged on the first side, is therefore arranged in the first chamber.
- the at least one power module of the second inverter which is arranged on the second side of the plate section, is arranged in the second chamber.
- Each of the inverters may comprise one power module or multiple power modules, with the power modules of the first inverter preferably being arranged on the first side of the plate section and the power modules of the second inverter being arranged on the second side of the plate section.
- a plurality of power modules can be present, for example, if the inverters are each designed to generate and/or convert a multiphase alternating current, with one power module comprising a half-bridge made of two transistors being present per phase of the alternating current, for example.
- the arrangement of the power modules on the opposite sides of the plate section enables a compact arrangement of the inverters inside the housing of the electrical circuit arrangement.
- the plate section can extend centrally through the housing and the interior into two equal parts share large or at least substantially equal chambers.
- the Plattenab section can be designed as a part of the housing, which is taken for example in one piece with other sections of the housing or fastened to them.
- the plate portion as a support portion for the circuit elements of the inverter enables a small-sized design of the housing. It is also possible for the housing, in particular the plate section, to consist of an at least partially or partially electrically conductive material, so that there is also a shield between the first chamber and the second chamber and thus between the first inverter and the second inverter can be generated. In this way, interference caused by the switching operations of the transistors in the power modules can be shielded from the other inverter.
- the compact arrangement of the inverters in a housing is particularly advantageous when the electrical circuit arrangement is used in a motor vehicle, since the overall space available inside a motor vehicle is severely limited. In this way, the use of the electrical circuit arrangement as part of an electrical axle of a motor vehicle is advantageously simplified.
- the two inverters can be used in particular to operate two electric machines, which are each assigned to one wheel of the motor vehicle.
- the arrangement of the first inverter and the second inverter in a common housing and in particular the arrangement of the power modules on the opposite sides of the plate section make it advantageous that the number of other components of the electrical circuit arrangement can be reduced, since the spatially adjacent arrangement of the Inverter sharing of the components is possible, as will be described in more detail below. Furthermore, the cooling of the inverters and in particular their power modules is simplified since only the shared housing has to be connected to a cooling circuit, for example the cooling circuit of a motor vehicle, in order to dissipate the heat generated in the power modules during operation of the inverters.
- the direct current sensor can measure a direct current supplied to or generated by the inverters.
- the direct current sensor can be arranged inside the housing, for example in the first chamber or in the second chamber.
- the plate section has at least one cooling channel extending inside the plate section.
- the plate section can have one or more cooling channels extending inside the plate section.
- the plate section can thus be a cooling plate which can be used to cool the components arranged on the sides of the plate section, in particular the power modules of the inverters.
- the cooling channel or the several sections of a cooling channel that are in particular connected to one another inside the plate section can be connected to a cooling circuit, for example a water cooling circuit, of a motor vehicle via one or more connections on the housing side.
- At least one inlet and at least one outlet can thus be provided on the housing of the electrical circuit arrangement, which communicate with the at least one cooling channel inside the plate section and enable the supply of a cooling medium such as cooling water or cooling air.
- the power modules each have a heat sink, with the power modules each being arranged with the heat sink on the plate section, with a cooling medium being able to be supplied to the heat sink via the cooling channel of the plate section.
- the heat sink of the power modules can, for example, have a meander or fin design Have structure which delimit a further ren cooling channel with the respective side of the plate section.
- At least one opening can be provided in the plate section, for example, which leads to the cooling channel running inside the plate section.
- the heat sink of a power module can be arranged on or in this opening, so that the cooling medium can be fed to the heat sink or to a further cooling channel delimited by the heat sink and the plate section.
- the DC sides of the first inverter and of the second inverter are connected to a capacitor arranged in the first chamber and in particular on the first side of the plate section.
- a capacitor arranged in the first chamber can be used, for example, as an X-capacitor and connected in parallel to the terminals on the DC side, for example a DC + and a DC - terminal, of the first inverter.
- Connecting the direct current side of the second inverter to the direct current side of the first inverter or to the capacitor makes it possible for the second inverter circuit arranged in the second chamber to be able to use the capacitor arranged in the first chamber.
- the capacitor has an increased capacity compared to a capacitor used only for an inverter.
- a second capacitor can advantageously be dispensed with, since the first inverter and the second inverter can be connected to the same capacitor. As a result, the size of the electrical circuit arrangement's can be advantageously reduced.
- first chamber and the second chamber are used here to describe the arrangement of the components of the electrical circuit arrangement in the various chambers, which are inside the housing by the Plate section are formed. It is possible that the components arranged in the first chamber are also arranged in the second chamber and vice versa. It is also possible to divide one of the components into a number of sub-components, for example a capacitor into two sub-capacitors. A sub-component or a sub-condenser can be arranged in the first chamber and a further sub-component or a further sub-condenser in the second chamber.
- the capacitor is connected to the DC side of the power module of the second inverter via at least one busbar, with the busbar extending through a recess in the Plate section extends.
- a busbar can z.
- B. connect at least one DC-side connection or at least one DC contact of the power module of the first inverter to a DC-side connection of the power module of the second inverter, the capacitor being connected, for example, to the DC-side connections of the power module or the power modules of the first inverter. In this way it can be achieved that the capacitor is also connected in parallel to the direct current side of the second inverter.
- the busbar is designed as a laminated busbar comprising a plurality of conductive metal sheets.
- the individual conductive sheets of the busbar are particularly insulated from one another, with the sheet metals of the busbar alternately carrying a positive and a negative potential or alternately connecting the DC + and DC - connections of the inverters to one another.
- the laminated, conductive metal sheets can each have contact lugs protruding on different sides, via which the majority of the conductive metal sheets of the busbar assigned to the different poles can be contacted in each case. In this way, a low-inductive, compact design that generates only a comparatively small interference field can be achieved for the busbar.
- the DC sides of the first inverter and the second inverter are connected to a filter circuit arranged in the second chamber.
- the filter circuit can be connected, for example, to the DC side of the second inverter and/or to a capacitor connected to the second inverter.
- the filter circuit can include one or more filter elements, which in particular filter the AC components at the switching frequencies of the inverters and/or their harmonics. This enables a compact design of the electrical circuit arrangement, in particular when using a capacitor arranged in the first chamber.
- the filter circuit can include multiple filter components. It is also possible that the filter circuit is arranged in the first chamber or that the filter circuit has several filter components, with at least one filter component being arranged in the first chamber and at least one filter component being arranged in the second chamber.
- a shielding element is arranged between the filter circuit and the power module of the second inverter.
- the shielding element can divide the second chamber into two sub-chambers, so that the filter circuit is shielded from the power module of the second inverter. In this way, the filter effect of the filter circuit can be improved.
